We present analytical and numerical solutions which describe a hot, viscous, two-temperature accretion flow onto a rotating neutron star or any other rotating compact star with a surface. We assume Coulomb coupling between the protons and electrons, and free-free cooling from the electrons. Outside a thin boundary layer, where the accretion flow meets the star, we show that there is an extended...

The importance of various factors relating to the preparation of polyacrylamide flocculant solutions was investigated. For optimum results, these solutions should be agitated for at least 2 hours before use while water of high ionic content should be avoided. The quantity of calcium phosphate precipitated during the clarification reaction and the calcium concentration in clear juice are shown t...

Ongoing research at the University of Leeds, being undertaken as part of the DIAMOND university consortium, is exploring the effectiveness of various ultrasonic technologies as in situ probes to characterize and monitor simulant nuclear wastes. Through use of a commercial Ultrasonic Velocity Profiler (UVP) and an Acoustic Backscatter Sensor (ABS) both with 1 – 5 MHz transducers, various propert...
